Replacing the 8/40 SAN Switch power supply and fan assembly

CAUTION:
Disassembling any part of the power supply and fan assembly voids the warranty and regulatory
certifications. There are no user-serviceable parts inside the power supply and fan assembly. Because
the cooling system relies on pressurized air, do not leave any of the fan assembly slots empty longer
than two minutes while the switch is operating. If a fan assembly fails, leave it in the switch until it
can be replaced. Maintain all fan assemblies in operational condition to provide redundancy.
Replacing the power supply and fan assembly unit takes approximately two minutes. You will need:
New power supply and fan assembly FRU (one unit)
Phillips-head screwdriver #1
To replace the power supply and fan assembly unit:
1.
Use a Phillips-head screwdriver to unscrew the captive screw on the power supply fan assembly
you are replacing.
2.
Remove the power supply fan assembly you are replacing from the chassis by pulling the handle
out and away from the chassis.
3.
Install the new power supply fan assembly unit in the chassis:
a.
Orient the new fan assembly with the captive screw on the right.
b.
Gently push the power supply fan assembly into the chassis until it is firmly seated.
CAUTION:
Do not force the installation. If the power supply fan assembly does not slide in easily,
ensure that it is correctly oriented before continuing.
c.
Secure the fan assembly to the chassis by screwing in the captive screw.
